stop using gas ? ...

But they do take the trouble to wear a mask before they go out stabbing

Not in Aberdeen and Northumberland. The damage to HV lines is pretty bad. Not just trees blown onto power lines, but wooden poles holding up 11Kv lines snapped like matchsticks. Maybe they should have replaced those 50-YO poles earlier in their life though ?. Thank goodness BT and the energy companies are still allowed to use proper creosote, or there could have been many more snapped poles.

and us mugs have to use creocote

the exception proves the rule

Yes, 'standard' PTO speed is 540rpm (I wonder why?) and some tractors (like my Kubota) also have 1000rpm. It is of course dependent on engine speed so my '540 rpm' PTO is actually engine rpm divided by four (or very close to that ration). I guess really big tractors may have some clever variable ratio system to provide a constant 540rpm.

:-) My father had a 25D (twin seat and clutch/brake on the same side of the gearbox). Pistons seized in the bores after being left standing. Freed off by whacking the pistons tops with a lump of wood. Ran well for several more years before sale to some tree surgeons. Some DB fan would still pay money!

We had replaced our wooden poles with the 11KV lines on them with concrete ones and had one of them blown over in our megastorm.

The new estates have everything underground.

How about an inverter generator? I wonder if anyone had produced such a beast that will run from a PTO. It would be a wizard thing to have.

A quick google suggests that PTO generators produce 50Hz from pretty well any PTO RPM. I'm looking at one that quotes 435RPM.

Shouldn't really use electronics from non-sinusoidal power. No need when true sine inverters are available.

Don't know:-) Some sort of inverter? Where are our resident experts?

In the end undergrounding is just lower maintenenance. "No new overhead

Hmm. I have about 1200m of 11kV running through the farm. Originally all on pre war lattice steel towers. Where it crosses the by-way there used to be a substation now replaced by an 11kV underground cable feeding a new outlet for the West side of the village. Half the towers have been replaced with timber poles and the stretch nearest the village undergrounded. Possibly on the basis the land might be developed.

there are plenty of PTO generators available - some with monstrous power outputs (50kW!). Not sure how common inverter based ones are.

PTO?

Power Take Off.

Power take off. The spinny bit on the back of tractors.
